SPECIFICATION forming part of Letters Patent No. 295,228, dated March 18, 1884,

V Application tiled January S, 1584. (No model.)

' Illinois, have invented certain new and useful g Improvements in Springs for Vehicles; and I i do hereby. declare that the following is a full, i clear, and exact description of the invention,

which will enable others skilled in the art to which it appertains to make and use thesame,

reference being had to the accompanying drawings, and to letters oi' reference marked there1 on, which i'orni a part oi' thisspecitieation.

My invention, which consists in a special construction oi" spring and in its application to the vehicle, will be readily understood from the following: f

Figure l illustrates a part of a vehicle with iny improved springs Aapplied thereto. Fig. 2 is a perspective View ofthe spring. and Fig. 8 is a section through the line u u. oi' Fig. l.

A is-the upper half oi my improved spring, made somewhat in the shape oian Indian bow, and having its central part, b, substantially straight, and its extremities c curved, and preferably curved upward, as shown; and I connect with this one or more shorter leaves, 1, attached to its under side.

D is the lower halt' of my spring, of a shape l similar to the upper half, A. and coupled at.

its ends to the ends of the half A by an ordinary button or shackle, and this halt' D may have one or more shorter leaves, 2, attached to its upper side. This construction, as will now be observed, renders it applicable for having the portions A D pressed or pulled apart from each other when in use, insteadof being compressed toward each other after the usual nianner of elliptic and similar springs.

My mode ofconnecting this improved spring to avehiole is as follows: Taking a two-wheeled vehicle or village 'or dog cart as an illustra tion, the upper halt' or portion, A, I connect at its straight part b to the axle and shafts by rigid braces or supports 3 et 5 underneath the spring, the supports 3 and et diverging upwardV from the axle and supporting the 'spring firmly, and the supports which connect to the shafts at points forward of the axle, serve also as braces for the whole structure.

Thus far, as will be seen, the body of the vehicle has noy relation to the spring, as rit is not directly connected to nor does it rest on the upper portion, A. On the contrary, the body rests on or is suspended either from the upper or lower side ofthe lower half, D, and at its central or straight part, about six to eight inches each side of center; and this i straight part gives a drin and extended support, as distinguished i'roni connecting the spring at a single point.

When in use, the weight of the load comes directly on the lower half, D, and this action pulls the portions A and D in a direction away l i from each other, instead of pressing them nearer together.

l Beneath the lower half, D, of the spring, I l attach an additionalshort spring, fr, with one i or more leaves, y. i

t The body ot' the vehicle is arranged to be l adjusted higher or lower, with reference tothe different sizes of horses, by means oi' the supports ai oi' the body, and in which jacks are l made one or more holes, m2. one aboye another, l to receive the bolts as, which are connected to i the respective'ends of. loops to". rlhe short i spring x, I clip to the lower side of the lower half, D. By these means either the front or l the back ofthe body, or both front and back,

may be raised orlowered, as desired.

The described spring may be used in a reversed position-that is, with the part A beneath the part D, or, in otherI words, upside down. In such ease, however, the loops fr* and the jacks ai and bolts as will be evident, will be at the top ofthe spring. In this reversed position the spring will act as a compressed spring.

struction and arrangement, as tirst above described, the following may be named: The greater the load the farther apart are the portions A and D, and the battering and hainmer ing which attend a compressed spring when fully compressed are absolutely avoided, for every increase of the load upon my spring spring to come into contact.

It will be seen that this spring, with its braces 3 4 5, contributes much to the strength and durability oi' the vehicle, and that as the weight comes directly on the lower half, while any rocking or, horse motion would be m- Besides other advantages due to my conlessens the liability oi' the members oi' thev IOO parted not directly to such lower half, but to the upper half only, the body will be compara'- tively free from suoh'rnotion.

My improved spring may be applied toa great Variety ,of Vehicles, and where there are no shafts extending back to the axle the b raee may at its lower end rest on any other oonvenient part of the vehicle.

My invention is especially of value in all vehicles where the load is to be supported directl y underneath the center of the load and of thespring. Y

I elairnp 1. The vehicle-spring Constructed as described-that is, of the two parts or halves A and D` each having'a Central part substantially straight, terminating at each end in a curve, these parts being jointed at their eX- trernitie's, the upper half having leaves on its under side, and the lower halt' having leaves on its upper side-the springs being` applied to the vehicle with the body or Weight Connected directly underneath to the lower half, D, and with the additional springs underneath the lower half, as shown and described.

2. In Combina-tion, the described spring,co11- sisting` of the parts A and D,eonstrueted as set (forth, the braces 3 and 4l, Connecting the upper part, A, to the axle, the braces 5, connecting the same part to the shafts, and the body supported by or upon or underneath the lower half7 D, 0f the spring'.
